Marine biology

Marine biology is the study of any living plant or animal in the sea. Marine biologists are the people who study it. Like other scientists, marine biologists must know a lot about the creatures they are studying. They also must understand how the sea works. The study of how the sea works is oceanography. There are many kinds of marine animals and plants to study.

Marine animals include squids, corals, whales and fish. Marine plants include sea grasses and algae. The Census of Marine Life was a ten-year project of marine biology.
